Heterogeneity in decentralized asset markets

Heterogeneity in Decentralized Asset Markets∗

We consider a decentralized market for an asset (or durable good) where investors’ valuations are heterogeneous and drawn from an arbitrary distribution. We provide a full characterization of the equilibrium, in closed form, both in and out of steady state. We find that investors with moderate valuations tend to specialize in intermediation, so that a “core-periphery” trading network emerges en...

The Effect of Intermediaries’ Market Power in Decentralized Asset Markets

This paper shows that the presence of intermediaries’ market power in decentralized asset markets reduces volumes traded and increases price volatility. I develop a method to estimate the degree of intermediaries’ market power from trading data and I apply it to the US municipal bond market using a new dataset containing all trades executed in this market. I find a high degree of dealer market ...

Search in Asset Markets

We investigate how trading frictions in asset markets affect portfolio choices, asset prices and efficiency. We generalize the search-theoretic model of financial intermediation of Duffie, Gârleanu and Pedersen (2005) to allow for more general preferences and idiosyncratic shock structure, unrestricted portfolio choices, aggregate uncertainty and entry of dealers. With a fixed measure of dealer...
